Plastic Pandemic: The Ecological Fallout of COVID-19 and Policy Options for Sri Lanka

The lockdowns introduced in 2020 to curb the spread of COVID-19 saw the narrative “nature is healing” gain prominence. However, the notion that nature, in the absence of people, was healing fizzled out fairly quickly with the emergence of fresh environmental challenges, most notably, the resurgence of single-use plastics. This blog examines the ecological fallout of the pandemic and suggests policy options for Sri Lanka to avert the looming environmental disaster.

Healing the Ozone Layer: The Need for a National Cooling Policy (NCP) for Sri Lanka

The ozone layer is located in the lower stratosphere at a height of 15 to 30 kilometres above the earth, protecting it against the sun’s harmful ultraviolet (UV-B) radiation. It is like a blanket that protects the planet; a reduction in ozone concentration increases solar radiation damaging plants, animals, and human beings. Human-induced depletion of the ozone layer due to excessive emissions of ozone-depleting substances (ODS) which are primarily used in the cooling sector is a major global environmental concern. This blog discusses the importance of a National Cooling Policy (NCP) for Sri Lanka as a part of IPS’ ongoing research, to phase out ODS to prevent ozone depletion and mitigate global warming.

Forest Restoration: Where Does Sri Lanka Stand?

This year, the International Day of Forests is marked under the apt theme “Forest restoration: a path to recovery and well-being”.  Forest restoration is one of the priority areas for mitigating the effects of climate change. Restoration and sustainable management of forests will help absorb atmospheric pollutants, re-build natural habitats and sustain life on earth.
This blog discusses Sri Lanka’s declining forest cover and offers suggestions on how the drivers of deforestation can be countered.

Urban Solutions: Building Pandemic Resilience in Sri Lanka’s Cities

Sri Lanka is experiencing a second wave of the COVID-19 pandemic, and cities and urban centres have become the hotspots of vulnerability. With their relatively favourable economic conditions and extensive transport networks, cities attract migrants from rural areas, frequently resulting in overcrowding and greater vulnerability to external shocks such as COVID-19. Hence, strengthening resilience of cities and urban settlements to meet health emergencies is a critical part of the national response strategy to pandemics. This blog explains why cities should be focal points of pandemic response planning, and discusses ways to build pandemic resilience in Sri Lanka’s urban areas.
